#include <Wire.h>#define MAX30100_ADDRESS 0x57void setup() {
Serial.begin(9600);
Wire.begin();
}void loop() {
byte heartRate;
byte spo2;// Read heart rate and oxygen saturation data
Wire.beginTransmission(MAX30100_ADDRESS);
Wire.write(0x00); // MODE_STAT register
Wire.endTransmission(false);
Wire.requestFrom(MAX30100_ADDRESS, 2);
heartRate = Wire.read();
spo2 = Wire.read();// Print heart rate and oxygen saturation data
Serial.print("Heart Rate: ");
Serial.print(heartRate);
Serial.println(" bpm");
Serial.print("Oxygen Saturation: ");
Serial.print(spo2);
Serial.println(" %");
Serial.println();delay(1000);
}
```### Example 2: Read Raw Data using Raspberry Pi (Python)This example demonstrates how to read raw data from the MAX30100 module using a Raspberry Pi and Python.```python
import smbus
import time# Initialize I2C bus
bus = smbus.SMBus(1)# MAX30100 I2C address
max30100_address = 0x57while True:
# Read raw data (6 bytes)
raw_data = bus.read_i2c_block_data(max30100_address, 0x04, 6)# Print raw data
print("Raw Data: ", end="")
for byte in raw_data:
print(f"{byte:02x} ", end="")
print()time.sleep(0.1)
```### Example 3: Interrupt-based Heart Rate Monitoring using ESP32 (C++)This example demonstrates how to use the interrupt pin of the MAX30100 module to detect new heart rate data and read it using an ESP32 board.```cpp
#include <WiFi.h>
#include <Wire.h>#define MAX30100_ADDRESS 0x57
#define INTERRUPT_PIN 2volatile bool newDataAvailable = false;void IRAM_ATTR handleInterrupt() {
newDataAvailable = true;
}void setup() {
Serial.begin(9600);
Wire.begin();
pinMode(INTERRUPT_PIN, INPUT);
attachInterrupt(INTERRUPT_PIN, handleInterrupt, RISING);
}void loop() {
if (newDataAvailable) {
byte heartRate;// Read heart rate data
Wire.beginTransmission(MAX30100_ADDRESS);
Wire.write(0x00); // MODE_STAT register
Wire.endTransmission(false);
Wire.requestFrom(MAX30100_ADDRESS, 1);
heartRate = Wire.read();// Print heart rate data
Serial.print("Heart Rate: ");
Serial.print(heartRate);
Serial.println(" bpm");newDataAvailable = false;
}
